Also remove the need to use bp2build_available on
soong_config_module_types as we want to convert every single of them
into the tree for a complete soong_injection soong_config_variables.bzl
file.
The variables are split into their bool, value and string types
respectively, as they all need to be handled differently on the Bazel
product_platform side, as well as for generating constraint values and
settings. For example, value variables need to integrate with
TemplateVariableInfo, and string variables need to include the string
value itself into the select key/constraint value.

variable usage.
There's bug a in the current soong_config_variable handling
implementation where a soong_config_variable sets conditions_default
value for an attr, and a non-conditions_default value for another attr.
This results in the former attr not properly setting the zero value for
the non-conditions_default select key, resulting in the pretty printer
omitting the attribute totally.
The current implementation in this CL ensures that the zero value is set
whenever this happens at the module level. This is seen in
library_linking_strategy_cc_defaults (see comments in code, and the new
tests)

string key with hardcoded patterns.
This fixes a bug with label list conditions_default attrs where the
attribute values get clobbered in a map with the keys
"conditions_default" (with a default empty list) and
"acme__feature__conditions_default" (with a non-empty list) when
generating the LabelListAttribute.

The generated_header property resides in BaseCompilerProperties, while
export_generated_header resides in BaseLinkerProperties. Previously
bp2build handled these property structs separately; however, these two
related properties residing in separate structs requires restructuring
the code to allow access to both BaseCompilerProperties and
BaseLinkerProperties for a single axis/configuration combination to
resolve which generated headers are exported/not for the
axis/configuration..

This converts cpp_std and gnu_extensions into a -std copt, if cpp_std is
specified or gnu_extensions is false if cpp_std is not specified.
I chose to go with this copts approach because the tradeoff is a much
simpler setting than adding a new attr(s) everywhere that uses features
to set the flag.
This approach limits the number of user-configurable knobs (since users
would then be able to set std in _both_ copts and the new attr). But it
does rely on the user copt overriding the toolchain's default gnu++17
version, which can mean a `-std` flag showing up twice in the action.

If nocrt is true, then the compilation for cc_shared_library,
cc_binary (shared or static binaries) will _not_ link against their
respective crtbegin and crtend libraries.
nocrt is true only for the Bionic libraries themselves. For everything
else that links against the Bionic runtime, crtbegin and crtend
libraries are used. This makes the "nocrt: false" case the majority.
Hence, if nocrt is explicitly false, we omit the generating attribute in
bp2build.
If nocrt is explicitly true (link_crt is false), the Starlark macro will
disable the link_crt cc_toolchain feature.

this list must also be within a shared/static/whole_static/header libs

prepended with implementation_, those in export_.*_headers will not have

Previously, when referencing a cc_library as a static_lib from a
converted module, the corresponding target would depend on the "root
target" of that cc_library. This resulted in a superfluous dependency on
the shared target of the cc_library dependency. This superfluous
dependency could sometimes result in cycles.
This change ensures the static target name is directly specified in such
cases.
